From 1898 to 2011, two sets of letters pertaining to one Jack Harkness... and the troubles he brings along with him. Post- and pre- canon, Jack/Constantine... well, Jack/everyone, really. With lots of shoutouts to other fandoms.

What if the third door had not led to Jack Mort at all, but to another? A man as cynical, battle-hardened, and ruthless as Roland himself - what if it had led to John Constantine? Hellblazer/Dark Tower crossover, spanning most of the DT series. ABANDONED.
